Application December as, 1m, Serial No. 243.049 4o (Helms. (ct 21:45)

v The invention relates to methods of and machines for labeling and has for its obiect to provide a novel and simple method whereby labels. and more particularly relatively stiff labels, may be emciently and uniformly applied L the articles for which said labels are intended. The invention has for its further object to provide a novel machine for carrying out. the novel method and whereby labels are adhesively and uniformly applied to articles in predetermined positions thereon. A further object of the invention comprises the provision of a labeling machine for adhesively applying labels having inherent characteristics rendering application thereof diiiicult to articles in an efllcient and uniform manner. The invention contemplates particularly a labeling machine for emciently connecting labels having an inherent stillness tending to maintain and restore said labels in and to a normal fiat condition, adhesively to a plurality of surfaces of said articles located in transverse relation to each other. Other more specific objects will appear from the description hereinafter and the features of novelty will be pointed out in the claims.

In the accompanying drawings which illustrate an example of the invention without defining its limits, Fig. l is a front elevation of the novel labeling machine; Fig. 2 is a side elevation thereof partly in section; mg. 3 is a side elevation looking in a direction opposite to Fig. 2; Fig. 4 is a plan view; Fig. 5 is a horizontal section on the line 5-5 of Fig. 1; Fig. 8 is an elevation of a pressure mechanism whereby the labels are adhesively connected with the articles; Fig. 7 is a sectional elevation on the line 1-1 of Fig. 6; Fig. 8 is a horizontal section on the line H of Fig. '7; Fig. 9 is an elevation of the pressure mechanism with the parts in different positions; Fig. 10 is a fragmentary plan view illustrating an operative step of the pressure mechanism, and Fig. 11 is a fragmentary section showing a moistening means included in the machine.

In its preferred form the novel method consists in moistening each label on one surface thereof, then applying a coating of adhesive to them:- posite surface of said label to render the same adhesiveand to further soften saidlabel. 'lhe latter is then adhesively applied to an article and at the same time is again moistened to still further soften said label and to reduce any tendency of the applied label to detach itself from the article to a minimum. After the aforesaid adhesive application and coincidental moistening thereof, the applied label is subjected to heated pressure or pressure in the presence of heat to remove the moisture from said label and to complete the application thereof.

In order to simplifythe illustration and de scription, the novel machine is shown in a form adapted primarily for the application of labels, as exemplified by conventional excise revenue stamps, to the tops and opposite side surfaces of bottles or similar articles, it being understood that this is in no sense intended to define. the

range of usefulnessof the novel machine.

The illustrated machine comprises a supporting frame II of appropriate yp 'and dimensions on which a suitable container or hopper I8. is mounted in position for proper co-operation with the associated elements of the machine. The container or hopper it contains a supply of labels ill in the form of an upright stack from theupper end of which successive terminal labels are removed in individual sequence for application to the articles is for which said labels il are'intended. In the instant case, the labels II are exemplified by conventional excise revenue stamps and the articles it are exemplified by bottles to which said labels are adhesively applied so as to extend over the stoppers and two opposite upright surface portions oi said bottles ll as shown in Fig. 9; when fully applied, the

labels I! are thus of inverted U-shape and prevent tampering with the stoppers of said bottles is without damage to the labels ii in the conventional manner. Because of the inherent stiii-' ness of thelabels II as exemplified by the afore- 3 said revenue stamps and the resultant tendency cated above, presents, dlillculties which are efliciently overcome in the instant machine as will be fully set forth hereinafter.

Any suitable provision may be made for pcriodlcally'restoring the upper end of the stack labels II, the container or hopper II is provided with a vertically adiustable bottom on which the stack of labels I1 is supported. The afore said bottom of the container or hopper i0 is carion fixed upon a shaft l9 journalled on the frame IS in any conventional manner. A ratchet wheel 20 is also secured upon the shaft 19 and may be intermittently operated by means of a pawl 21 and held against unintentional return movement by a stop-pawl 22 suitably pivoted upon the frame 15. The pawlvil is pivotally mounted upon an operating member 23 which itself is mounted to rock upon the shaft is and carries a roller 24 arranged to be operatively acted upon by a cam 25 fixed upon a shaft 26. rotatably mounted on the frame 15 in any convenient manner; a spring 21 acting on the mem-" ber 23 serves to maintain the roller 24 in operative relation to the cam 25. The member 23 is normally held against operation by means of a projection 28 in co-perati0n with a shoulder 20 formed on a controlling member 30 which is tripped to release said member 23 when the stack of labels l1 has decreased in height to a predetermined point. An arrangement 03 the kind described is shown in my co-pending application, Serial No. 113,796.

The stack elevating mechanism is controlled by means of a fee1er'3i arranged to enzale the upper end of the stack of labels l1, and vertically slidable in an upright guide 82 on the frame l; thefeeler Si is pivotally connected at 33 with a bell-crank lever 34 fixed upon a shaft 38 journalled on the frame l5 and provided with a roller it arranged in operative relation to a cam 31. The latter is secured upon a rock-shaft 38 suitably mounted on the frame it.

Because of the inherent stillness of the labels 11, as exemplified by conventional excise revenue stamps, it is desirable to soften the labels I1 in order to facilitate the application to the articles exemplified by the bottles it. For this purpose the terminal labels 11 in the supply stack are .moistened on the face thereof in any suitable es, the other side of which is connected for instance through the-medium of a tube 4! with a source of water or other suitable fluid under pressure; the operation of the valve or cook 44 may,

cook '44 will automatically return to its closed position to thereby shut oi! the supply of water or other fluid to the spray apertures 49.

In the machine as illustrated, the means whereby individual labels H are successively re.- r'noved from the top of the stack in the container or hopper I6, and transferred therefrom to the point of application to the articles exemplified by the bottle I8, is of the suction operated or vacuum type, and per se may be of any suitable construction. As shown, the label transferring means consists of a carriage 41 slidably mounted for reciprocation on a horizontal guide rail 48 supported on the frame I! in any convenient on its axis to correspondingly operate the arm for instance, be controlled by a lever 44 which projects into thejoperative path of the feeler 3| through the tube 43, nipple 42 and channel 4| to the chamber 40 of the feeler head ll; from said chamber 40 the water or other fluid issues through the apertures 34 in the form of'a spray whereby the face of the current terminal label l1 in the stack is moistened. As soon as the feeler ll, develops an operative upward movement as will be more fully described hereinafter,

the lever 48 will be relieved and the valve 01 48 and thereby efiect the reciprocation of the carriage 41 on the rail 48, may as shown in Fig.

3, comprise a toothed segment 54 fixed upon the shaft 38 and meshing with a rack 54. The latter is slidable in a guide bracket 65 suitably located upon the frame I5 and is vertically reciprocated in proper operative timing with the associated mechanism in any suitable manner, for instance, as shown in my previously mentioned co-pending application, Serial No. 113,796.

The carriage 41 supports a member 56 capable of vertical reciprocation thereon and provided at its lower end with a suction head 51 0! any suitable type and having a suction nipple 58 for accommodating one end of a suction hose 59 as illustrated in Fig. 2. The suction hose I59 is connected with one side of a valve casing supported upon the frame I! in any convenient manner and having its other side connected by means of a hose or tube 8! with a source of suction such as a pump or the like; the purpose of this arrangement will appear more fully hereinafter.

The member 56 is vertically movable on the carriage" at one end of the reciprocation thereof to pick up a terminal label 11 from the top oi the stack in the hopper i8, and at the other terminal of said reciprocation to dispose of the picked up label for application to a bottle 18 or other article. During the movement of the carriage 41 from the label pick-up station to the label disposal station the member 58 is held against downward movement on the carriage 41 by means of a roller 42 which travels along a fixed rail 83 recessed at the proper points to permit the desired downward movements of the member 88 and with it the suction head 51. Any suitable mechanism may be provided for operating the member" and suction head 51 in vertical directions, such as for instance disclosed in my aforesaid .co-pendin: application, Serial No. 118,796.

In the instant machine the labels l1 picked up This adhesive coat-' adhesive to successive labels instance, of an adhesive applying roll ably mounted in the machine in tangential re- I elevated and will pass over a condition of flexibility which facilitatestheir application to the bottles II or other articles.

For the-purpose of applying-did-coating of H. the machine includes adhesive applying means eonsistag$cr ceiving relation to a suitably mounted adhesive distributing roll I which vdips into a am ly of adhesive in a container II hired .in place in any convenient manner; The applying roll It is so located that a label head Il will pass in progressive tangential engagement with said roll during the travel from the pick-up station to the disposal station; the arrangement is such that during .a return travel of the carriage 41 the suction head and above said applying roll 03 and accordingly will not engage the same.

The machine in its illustrated form includes supporting means located at the disposal station for receiving successive adhesive coated labels II from the suction head I1 and for supporting-said labels 11 in predetermined applying relation to augmented by the I! carried by the suctionaasasse turning said members thereto.

For this purpose theillustr'ated machine is provided with a carrier movable in intermittent steps and carrier.

the bottles I! or other articles. In the selected example the aforesaid supporting means includes supporting members ll located in spaced registry at a common level for instance as shown in Fig. 2. During an operativecycle of the .ma- 4 chine, an adhesive coated label I1 is deposited by the suction head '1 upon said supporting members 61 with the opposite end portions of said label l l in temporary adhesive connection there with and the intermediate portion of said label l'l extending between and spanning the space between said supporting members 81. The arrangement is such thatthe label II will be supin predetermined label applying relation ported to the' article to which it is to be applied.as for instance, at a level coincidental with the upper surface of the stopper whereby the bottles ll are closed, as illustrated in Fig. 2; because of the a plurality of means whereby the articles to be labeled are held in place on said In the illustrated example. the carrier comprises a turntable ll having aplurality of upright receptacles I. located circumferentially at regularly spaced intervals and shaped and dimensioned to accommodate the bottles I. and to hold them in upright positions on said turntable II as indicated by dotted lines in Fig. 2; in the preferred arrangement. the means for holding the articles to be labeled. exemplified by the receptacles ll, will be dimensioned and shaped in accordance with the articles to be accommodated thereby. To enable different turntables with various types of holding means such as the receptacles IO to be easily substituted provided with in the machine, the turntable I! is removably connected with the mechanism whereby said turntable I! is rotatively actuated. In the form 'shown'in the drawings. the turntable It is attached. for instance. by means of screws or the like to a collar 18 which itself is secured to an upright shaft 12 by means of a pin ll or-its equivalent.v The shaft II is rotatively mounted in a bearing ll forming part of a bracket l2 suitably supported on the frame ll, said shaft ll being held in place in the bearing II by the collar II which rests upon the upper end thereof as shown in Fig. 2. The shaft It projects downwardly beyond the'bearing Cl and carries a member 83 which preferably bears against the lower end of 'the'bearing ll'ito assist in holding the shaft II in place, and is provided with a plurality of rollers ll depending therefrom at spaced intervals as illustrated in Fig. 1. The rollers M are arranged for co-operation with a cam It secured upon the shaft 14 and provided with a groove consisting of a helical section I having an open entering end and a continuing circular section 81 concentric to the axis of the shaft ll to 9. depending web I which extends between and is carried by levers I. fixed upon and projecting upwardly from a. rock shaft "I. suitably Journalled on the frame Ii. For the P1 111 of adjusting the supporting members I! from an p r ive l b l pnlyinsposition to an inoperative position to permit the bottles ll or-other articles to be brought to labeling position withoutinterference, the shaft 1| also carries an arm ll provided at its free end with a roller I2; the latter projects into the cam groove of a cam II mounted upon a shaft 14 iournalled in the frame It, said cam ll acting on the roller II in a manner to rock the shaft IO and thereby adiust the supporting members I to and from their operative positions as will be more fully set forthhereinafter. A spring ll may be connected with one of the levers II and with a pin on the frame imthe direction of rotation thereof and terminating in an open exit end as in Fig. 5.

In the example of the machine selected for purposes of illustration and description, the carrier or turntable 1| is provided with five receptacles I. located at equally, spaced intervals circumferentially of. the turntable II as shown in Pig. 5-. Inthe operation of the machine, the turntable fl is intermittently rotated in successive steps whereby the receptacles I! are progressively brought to successive stations at which successive steps in the operative cycle are performed; it will be understood that each intermittent advance of the turntable II is followed by a periodof rest of suflicient time duration to enable the various operative steps to be carried out. For instance. in the instant installation, a bottle It is placed in a receptacle I. at the feeding station A in Fig. 5 and is then advanced to'the index-eta tion' B; from the latter the bottle II is carried to the first label applying station C and from there to the second label applying station D, after which the labeled bottle ll passesto the removal station E. 1

ror the purpose of determining the presence of us for maintaining the supporting members it a bottle It in a receptacle n and controlling h the labeling station at which the operation ofthe mechanism accordingly, the machine includes an indexing means which is operatively eil'ective at the index station B. In the form illustrated in the drawings, this indexing means includes an index lever provided at its one end with an index member 80 for instance as shown in Fig. 5. The lever 00 is arranged to be pivotally rocked and for this purpose is pivoted at 80' on the frame I and, is influenced in. one direction by a spring 00 as illustrated in Fig. 2. The opposite end of the lever 00 is pivotally connected at 0| with one end of a link 92, which at its other end is pivotally attached at 03 to an arm 94 fixed upon a shaft 33 suitably iournalled on the frame IS. The shaft 05 further carries a bell-crank lever 06 one arm of which is provided with a roller 81 normally acted on by a suitable sesame Serial No. 113,796. The aforesaid movable rail is operatively controlled also as set forth in said co-pending application, and similarly includes a lever or bracket IIO which carries said movable rail 4 as shown in Fig. 4, and is pivoted at II! on the frame I0. The lever or bracket H0 is pivotally connected at II1 with an operating member Illslotted at IIO for the accommodacam 98 fixed upon the shaft 14; the other arm of the lever 96 is connected by means of a link 00 with a control-member I00 which is pivoted at IN on the frame II and extends upwardly from said pivot IOI as shown in Figs. 2 and 3. If at any timeduring the operation of the machine, the turntable 16 fails to bring a bottle I0 to the index station 3 for instance because the attendant neglected to place a bottle I0 in one of the receptacles at the feeding station A, the indexing means will function to control certain operative steps accordingly as will appear more fully hereinafter.

The previously mentioned valve casing 00, in addition to its connections with the suction hose 5'0 and the tube BI, is provided with an-opening and a cc-operating valve I02 whereby communication between the valve casing 00 and the atmosphere is controlled, the arrangement being such that no suction will be developed in the suction head 51 when the valve I02 is in its open position. The valve I02 is carried by one arm of a bellcrank lever I03 pivoted at I04 upon a bracket I05 fixed upon the frame I5, a suitable spring I06 serving to urge said valve I02 to its open position. The other arm of the bell-crank lever I03 extends between two adjustable projections, shown in the form of screws I01 and I03, carried by spaced lugs I08 forming part of or secured upon a tripping member H0. The latter is suitably guided in vertical directions, and is formed with a lower forked end III which straddles the shaft 26 as shown in Fig. 3. The tripping member IIO further carries a roller H2 in rolling engagement with a suitable cam 'II3 fixed on the shaft ;a spring II4 acts on the tripping member I I0 in a manner to maintain the roller H2 in operative contact with the cam II3. As illustrated in Fig. 3-the upper end of the control-member I00 is normally located at a point between the depending legs of the forked end II I of the tripping member IIO; under the influence of the indexing means, the control-member I00 is arranged to be pivotally operated to bring its upper end into the downward path of one leg of the forked end III to thereby prevent downward operation of the tripping member IIO when no bottle I8 is present at the indexing station 3, as will be more fully set forth hereinafter.

The vertical movements of the suction head 01 relatively to the carriage 41 to pick up successive terminal labels I1 from the supply stack-and to dispose of the picked up labels for application to the bottles I0. or other articles, may be controlled by means nf a movable rail II4 associated with the fixed rail 03. and a second roller III similar to the roller 02 in the same way as shown tion of the shaft 26 and provided at its lowerend with a roller I20 in rolling engagement with a suitable cam I2I fixed upon the shaft 23. The previously mentioned spring II 4, in addition to its other functions, acts on the member II 0 in a manner to maintain the roller I20 in contact with the cam I2I; as shown in Fig. 3 the spring I I4 is connected at one end to the tripping member H8 and at its other end to the operating member II8.

For the purpose of controlling the vertical operation of the suction head 51 in dependence upon the proper picking up of a label I1 thereby, the operating member H0 is provided with a projection I22 arranged to co-operate, under certain conditions, with an associated projection I23 located on the bell-crank lever I03 in a manner to prevent vertical movement of the operating member H8 in the same way and for the same purposes as set forth in my co-pending application, Serial No. 113,736.

In addition to the parts so far described, the machine includes a first applying means for effecting the initial application of a label I1 to a bottle I0 or other article, and located at the first applying station C. As shown, this applying means comprises a slide-member I24 slidably mounted in a vertical gui deway I25 fixed upon the frame IS in any convenient manner, and

including preferably removable side members I20 and described in my co-pending application,

whereby the slide-member I24 is slidably maintained in the guideway I25. The slide-member I24 carries a guide bracket I21 which preferably is removably fixed in place by screws I28 and includes bearings I29. A pressure slide I30 carrying a suitable pressure device I3I at its lower end is slidably mounted in said guide bracket I21 in surface engagement with the slide-member I24 and slidable relatively thereto as will appear more fully hereinafter. A spring I32 has its one end connected with the guide bracket I21 and its other end attached to the pressure slide I30 and causes the pressure device I 3| to develop an operative pressure on the label I1 in the application thereof to the bottle I8'or other article, as will be more clearly described hereinafter. In addition to the above, the applying means includes pressure levers I33 pivotally mounted at I34 in the bearings I20 and continued in the form of oppositely directed arms I35 which intersect each other as shown in Figs. 6 and 9 and terminate in depending ends I 36 to which pressure pads I31 of suitable yielding in character are secured in any convenient manner. The ends I30 are preferably constructed in a manner .to supply fiuid to the pressure pads I31 to rende'r'the same moist, and, as shown, are provided with interior channels and communicating nipples I 30 for the accommodation of tubes I39 connected with a suitable source of moistening fluid. In the preferred arrangement, the pressure pads I31 in addition to being yielding in character may be shaped at least at their active surfaces to fit the surface of the bottles I0 or other articles to which the labels I1 material, preferably 'shown in Fig. 10.

and IN which project laterally from said levers in directions toward each other, and in superimposed overlapping registry with each other. In the preferred arrangement one of said lugs l or I449 carries an adjustable projection adapted to engage the other lug; in the illustrated construction, the adjustable projection is exemplified by a screw I31 threaded in the lug I3 and bearing against the lug I as shown in Figs. 6 and 9. A spring, I43 having its one end connected with an extension I33 of the lug I? and its other end attached to an ear I 33 on the operating member I serves to yieldingly maintain-said screw I41 or its equivalent in bearing contact with the lug I33.

gages the bearing pin I33 to thereby provide a resilient connection between said arm III and connecting rod I34. "The lower end of the latter is pivotally connected at I31 with one arm of a I33 pivoted at I33 on the frame I3 and having its other arm provided with a roller I33 projecting into the cam grooveof a 1 cam m secured upon the shaft 14.

- In the operation of the machine, the slide member I23 is slidably shifted in the guideway Any suitable mechanism may be provided for accommodation of nuts f one of which one end of a spring The latter in its 7 bracket I32 loosely mounted on first applyi s means at having spaced arms I33 and I33, the former of. which has itsfree end preferably rounded and located in a recess I33 formed in the slide member I23 for instance near its upper end. An a'ctuating member I33 is pivotally connected at I31'with the other arm I33 of the bracket I32, said am I33 preferably being provided with a slot I33 in which operative rocking movements of thebracket justed. The actuating member I33 is formed near its lower endwith a slot I33 for the accommodation of a bearing block I13 pivotally fixed on the frame I3 and serving to guide the member I33 in its operative movements. A suitable cam "I is secured on the shaft 23 and in co-operation with a roller I12 carried by the member I33 serves to operate associated elements. g

The machine furthermore includes additional applying means operating subsequently tothe the applying station C, and operative for instance at the second label applying station D.

correspond in construction and operation substantially to the first applying means located at the first applying station 0, and accordingly may include a slide member I23 slidably mounted in a vertical guideway I23 fixed upon the frame I3 in any convenient manner; as illustrated in Fig. 4, theslide member I23 may be slidably maintained in the guideway I23 by meansof removable side members I23 corresponding to the side members I23 of the first applying means.

, The slide member I23 carries a guide bracket I21 similar to the guide bracket I21 and likewise serving to maintain a pressure slide I33 corresponding to the pressure surface engagement with the slide member I23; the pressure slide I33 is influenced by a spring I32 similar to the spring I32 for the same purpose and in the same manner as in-the first applying means. The pressure slide I33 at its lower end carries a'pressure device corresponding to the previously described pressure device iii and functioning in a similar manner.

The guide bracket I23 includes bearings I23 in which pressure mounted, saidv levers I33, like the equivalent levers, I33 of the first applying means, being continued in, the form of oppositely directed arms I33 which intersect each other and terminate in depending ends I33 to which pressure pads I31 similar to sure pads I31 are secured in any suitable manner. As in the first applying means the pressure levers I33 are provided at their upper end with; rollers I33 and likewise are preferably connected at said upper ends bya spring similar to the spring I43 and in the same manner tend described hereinafter; in the selected example,

the heating means is diagrammatically illustrated as an electrical device connected with a source of electricity by means of the wires I33.

Throughout aportion of their length, the operating levers I44 and I44 are provided with outer side flanges I45 similar to the flanges I45 and likewise extending for a predetermined distance from the lowerends of said levers I 44 and I44"; the latter are further provided with opposed inner side flanges previously mentioned cam 98 fixed on the shaft For the purpose of supporting the turntable 15 and more particularly the receptacles 18 thereof from below at the respective applying stations C and D during the steps of applying labels I1 to-the bottles I8 or other articles, thebracket 82 is provided with supporting devices which project beneath and provide rests for the re- I48 extending in spaced parallel relation to the mounted in'a lug I 44 of the lever I44 and bear ing against a lug I44 of the lever I44 as shown in Fig. 3. A spring I48 corresponding to the spring I48 of the first applying means serves to yieldingly maintain the projection or screw I41 in bearing contact with the lug I44.

The operating levers I44 and I44 may be actuated in operative synchronism with the other elements of the machine by any suitable mechanism as for instance in a manner similar to that shown and described in connection with the first applying means. In the selected example, the operating member I44 constitutes an integral part of an arm Nil having a forked freeend I52 in which a bearing pin I53 is pivotally mounted. A connecting rod 154, similar to the rod I54, is slidably mounted in the bearing pin I53 and is yieldingly connected therewith by means of a spring I 56 and nuts I55 threaded upon said rod I54, as shown in Figs. 1, 2 and 3. The lower end of the connecting rod 154 is pivotally attached at I51 with one end of a rocking lever I58 pivoted at I 59 on the frame I5 and provided at its other end with a roller,l88 co-operating with a suitable cam I8I fixed on the shaft 14, as shown in Fig. 1.

During an operative cycle of the machine, the

islidemember I24 is slidably shifted in the guideway I to correspondingly actuate the pressure slide I80 and pressure levers I38 in properly timed relation to the other parts of the machine, by any suitable actuating mechanism which, as shown, may be similar to that of the first applying means. In its illustrated form the last named actuating mechanism ac'cordingly comprises a bracket I82 loosely mounted on the shaft 38 and including spaced arms I88 and I54, the former of which has its free end preferably rounded and located in a recess I 65 formed in the slide member I24 for ceptacles'18 located at the stations C and D respectively at any given time. In the illustrated example, the supporting devices are shown in the form of rigid, arms I13 extending radially outward from the bearing 8| and located so as to extend beneath two receptacles 16 each time the latter arrive at the stations C and D. The arrangement is such that said receptacles 18 rest upon said arms I18 at said stations C and D as shown in Fig. 2; to facilitate the supporting action of the arm I18, the receptacles 18 may be provided on the bottoms thereof with bosses I14 adapted to engage said arms I13 as illustrated in Fig. 2. From the above it will be clear, as the steps of applying the labels I1 to the bottles I8 I or other articles take place at the stations C' and D, that operative forces such as downward pressures exerted on said bottles I8 or other articles by the label applying mechanism, will be resisted by the arms I18 or their equivalent.

The machine may be operatively driven in any convenient manner, as for instance by means of a pinion I15 fixed upon a suitably mounted driving shaft I18 actuated in any conventional manner, said pinion being in mesh with a gear I11 secured on the shaft 26. The latter also carries a gear I18 which meshes with a co-operating gear I18 fastened upon the shaft 14, said gears I18 and I18 serving to transmit power from the shaft to the shaft 14 to operate the elements associated therewith.

In describing the operation of the novel'machine, it will be assumed that labels I1 exemplifled by conventional excise revenue stamps are being applied to the tops and necks of botties I8, it being understood that this is done for convenience and with no intent to'thereby define or limit the range of utility of said machine.

iWth the parts in the position shown in Fig. 2, the feeler head ll is in contact with the current terminal label I1 at the top of the supply stack, and the upper surface of said terminal label I1 is being moistened by the spray of fluid which issues through the apertures 88; it will be understood that the valve lever 48 is actuated at this stage by the feeler II to open the valve 44 whereby the aforesaid spray is controlled. By the actionof the cam 81 on theroller l6 and bell-crank lever 84, the feeler 8| is moved up and down in predetermined timing with the other steps in the operative cycle of the machine, and at the proper moment is elevated in the guide 32 to move the feeler head ll upwardly away from the supply stack of labels I1. As this upward movement takes place, pressure on the valve instance near its upper end. The bracket I82 further includes a member I84 preferably provided with a slot I88 in which a pivot pin I81 is adJustably mounted for pivotaliy and adjustabiy connecting one end of an actuating member I85 with the bracket I82 and through the latter with the arms I 85 and I84. The lower end of the actuating member I88 is forked at I88 to slidably straddle the shaft 14 and carries a roller I12 projecting into a cam groove formed an the 1 lever 48 is relieved and the valve 44 accordingly is closed to shut oi! the supply of fluid to the chamber 48 and thereby discontinue the spray through the apertures 85.

In proper operative synchronism with the above steps the suction head 51 is lifted on the carriage 41 to a level above the adhesive applying roll 84 or in other words, to a point above the intermediate position of said suction head 81 illustrated in Fig. 2; in this figure it may be assumed that the suction head 51 is being raised section 81 of the cam 85.

' try subsequent to the deposit thereby of a label I1 on the supporting. members 41 in position for application to a bottle I8 or other article. when.

the suction head has been raised to the proper extent, the carriage 41 will be shifted to the right on the rail 48 in Fig. 2 to bring the elevated suction head 51 to the pick-up station in verticalregistry with the supply stack of labels 11 in the hopper or container it; from the description hereinbefore, it will be clear that the feeler II cordingiy does not interfere with the position- 7 them 28 is removed whereupon the spring II will swing the index member it into engagement with the capped end of the bottle A and the tripping member I" will be operated by the action of the cam H2 and the spring H4 in a downward direction. This will cause'the upper prooccupies a raised position at this time and acing and operation of the suction head' 51 at said pick-up station.

By properly timed downward operation of the member ii on the carriage 41, the suction head .51 is correspondingly moved downwardly into surface contact with the current terminal label I1 at'the top of the supply stack, which terminal label I1 has previously received an initial moisjection I01 to act on the bell-crank lever I02 in a mannerfto close the valve I02 whereupon suction will be developed in the suction head 51. In

proper operative sequence the latter will, as described above, pick up a terminal label "from the 'supply stack, convey said label I1 in contact with the adhesive applying roller 64 to receive a coating of adhesive therefrom and deposit said adhesive coated label l1 on the supporting,

members 81 which have been movedinto operative position by the action of the cam 13 onthe roller 12, arm 1| and levers 69.

In the meantime, while the supporting members 41 and associated parts occupy inoperative positions out of the way, the turntable 15 has been rotated another step by the co-operative action of the helical section v86 of the cam 85 on ,one of the rollers 04. to shift the bottle A from raised on the carriage 41 to' thereby pick up or remove said terminal label I1 from the supply stack. The terminal label I1 thus picked up is raised-to a level corresponding to that of the adhesive applying roll 64, and the carriage 41 is moved toward the left in Fig. 2 on the rail 48; the

label I1 carried by the suction head 51 is thereby moved in progressive tangential contact with the adhesive applying roll 64 and receives a coating therefrom, which in addition to rendering the label I1 adhesive moistens the lower surface thereof. The movement of the carriage 41 is continued until the suction head 51 with the label I1 thereon is in vertical registry with the supporting members 81 at the label applying station of the machine.

In the meantime, a capped bottle A has been placed in upright position in a receptacle 16 at the feeding station A by an attendant, it being understood that the turntable 15 or equivalent carrier is at rest at the time. At the proper moment the cam 85 which is being rotated at the time will cause the entering end of the helical section 85 of said cam'li to engage one of the rollers 84 and at the same time to cause a companion roller 84 and the circular section 81 to become disengaged as will be apparent from an inspection of Fig. 5. As the cam}! rotates, the helical section 85 thereof 24 in a circular path to the left in Figs. 4 and and thereby will correspondingly rotate the turntable or equivalent carrier on its axis. As

- soon as the given roller 84 passes from the helical section 85 of the cam 85 into the circular section 21 thereof, the turntable 15 or equivalent carrier will come to rest and remain so as long as the aforesaid given roller 84 is in said circular The aforesaid rotative'movement of the turntable 15 is such as to shift the capped bottle A to the index station B in which the upper end of said bottle A is located beneath and in regiswith the index member 89 of the index lever The latter is h'eld in position. above the the bottle A against the tension at until a recess in the rotating with the roller 21 As'this stage 88. capped end of of the spring cam ll comes into registry carried by the bell-crank lever OI. resistance developed by the roller will move the one roller 91 riding on the index station B to the first label applying station C. After the adhesive coated label I1 has been deposited upon the supporting members 61 in theoperative position of the latter, said label l1 with its ends in temporary adhesive connection with said members 61 spans the space between the latter and is supported by said members 01 above and in label applying relation to the upright bottle A. In the illustrated example,

- the arm I62 of said bracket I82 in adownward dithe arrangement is such that at this stage the capped end of said bottle A is beneath and in registry with approximately the middle section of said label I1 so that the latter is supported in symmetrical applying relation to said capped end of said bottle A.

Because of the fact that the particular roller 84 rides in the concentric circular section 81 of the cam 85, the turntable 15 will remain at rest for a sufficient time period to permit the first label applying means at the applying station C to per-7 form its functions as follows: Through the cooperation of the rotating cam I1I andthe roller I12 a downward pull will be developed on actuating member I88 and transmitted to the arm I84 of the bracket I62 whereby the latter is pivotally swung on the shaft to correspondingly swing rection. The free end of the arm I63 will transmit this movement to the slide member I24 and cause the latter to move downwardly in the vertical guideway I2! and carry with it the guide bracket I21 and pressure levers I32 which are positioned relatively to each other as illustrated in Fig. 6 during these operative steps; at the same time the pressure slide. l 20 also moves downwardly with the slide member I24 and finally brings the pressure device Ill into engagement withthe intermediate portion of the label I1 which previously has been deposited upon the carrying members 01. As the aforesaid downward movements continue,'the pressure device Ill will force the intermediate portion of said label I1 downwardly into contact with the capped end of the bottle A, whereupon the downward movement of the pressure device HI and the pressure slide I30 will be arrested by said contact with the capped end of the bottle A as shown in Fig. 9; the slide-member I24 will however continue to move downwardly independently of and relatively to the pressure slide Ill, and the spring I22 will thereby be stretched under tension which is transmitted to the pressure slide I30 and pressure device I3I and causes the latter to firmly press the intermediate portion of said label I! into adhesive engagement with the capped end of the bottle A.

During the concurrent downward movements of the slide member I24 and pressure slide IN, the rollers I40 of the pressure levers I33 travel downwardly along the inner side flanges I46 and as the slide member I24 continues its independent downward movement, said rollers I40 will finally be-located in the channelled lower ends of the operating levers I44 and I44 between the outer side flanges I45 and the inner side flanges I46 thereof as illustrated in Fig. 9; the pressure levers I" are accordingly operatively connected with or coupled to the operating levers I44 and I44 as this point in the operative cycle is reached. As the pressure members I33 travel downwardly, the outer end portions of the label II will be engaged and withdrawn thereby from the supporting members 61 and will be bent or folded downwardly upon opposite sides of the neck of the bottle A;

at this stage the pressure pads I31 are correspo'ndingly locatedupon said opposite sides of the bottle neck.

In proper operative synchronism with the other mechanism at this stage, a downward pull is exerted on the connecting rod I64 by the action of the rotating cam groove IBI on the roller I60 and the bell-crank lever Ill, which is transmitted to the arm Ilil and pivotally swings the latter on the one pivot pin I43. The operating lever I44 is correspondingly swung on said pivot pin I43 and through the medium of the lugs I44 and I44 and the screw I4'I coincidentally swings the operating lever I44*-on the other pivot pin I43. As these pivotal movements of the levers I44 and I44 take place, the lower channelled ends thereof are moved toward each other and by acting on the rollers I40 through the medium of the outer side flanges I45, pivotally actuate the pressure levers I33 on the pivots I34 in directions to shift the pressurepads I81 toward each other, The downwardly bent or folded outer end portions of the label II are thereby-brought into engagement with the neck of the bottle A upon opposite sides said pressure pads I3? as shown in Fig. 9.

It will be noted that the latter are moistened so that the label H, which previously has been moistened at the pickup station and by the coat ing of adhesive applied by the roller 84 is again moistened by said pressure pads I31; the latter moistening by the pressure pads I31 takes place coincidentally with the application of the end porn tions of the label I! to the bottle neck. The stiflness normally inherent in said label I! is thereby still further reduced so that said label is readily manipulated in the indicated manner and at the same time developes no tendency to spring away from the bottle neck at this time.

When the pressure pads Ii'I-have performed their applying functions as set forth, the mechanlsm is actuated to swing the arm Iii upwardly and to thereby pivo'tally operate the operating levers I and I44, and consequently the pressure levers I" in reverse direction and to move the pressure pads I31 apart and away from the neck of the bottle A. At the proper time the slide member I24 is-moved upwardly in the guideway I25 by the arm I83 01' the bracket I82 which is pivotally swung on the shaft 38 through the medium of the actuating member I46, its roller I12, and the cam Ill to restore the parts to the position illustrated in Fig. 6. 7

By this time the particular roller 84 of the turntable II has moved out of the circular section 81 of the cam." and a successive roller 84 is ready to enter the helical section 48 of said cam As the latter continues its rotation, the turntable II is again rotatably operated to shift the initially labeled bottle A from the first ap- 10' plying station C to the second applying station D. At the latter station, the mechanical elements-comprising the additional applying means are operated under the control or. the actuating member I44", its roller mand the cam groove formed inthe cam 44 on the shaft 14 to vertically actuate the slide member I24! and its associated elements, and under the control or the connecting rod "4', rocking lever Ill, its roller I80 and cam' Ill on the shaft I4 to actuate the pressure P ds "1!, in substantially, thesame way as the elements of-the first applying means are operated at the first applying station C.

In any case, at the proper point in the operative cycle of the machine, the pressure device 25 carried by the pressure slide I34 is brought into engagement with that part. of the label H on the capped end of the bottle A, and is'caused to exert a pressure thereon whereby the application of this part of said label all is completed and the label as a whole is held against shifting on the bottle A. In proper, operative synchronism with the other operative steps. the pressure pads I31 are operated to develop applying. pressure to the end portions of said label H which have pre- 35 viously been initially applied to opposite sides of the neck of said bottle A. As the pressure pads I31- are heated, they subject the applied portions-of said label I! to the action of heat and thereby not only quickly remove the previously applied moisture therefrom. but at the same time set the adhesive coating oisaid label II: as a result, the application of said label I! to the particular bottle A is completed and said label is securely fastened thereto against any normal tendency to spring-away from said bottle.

' When the operations of the additional applying means has been completed, the turntable I! will again be rotated to transter the finally labeled bottle A from the second applying station D to the removal station E for suitable disposal by an attendant or by means of automatically co-cperating means.

It will be understood that as the turntable I8 is operated, successive bottles A or other articles will be carried thereby to the various stations in consecutive relation so that the operative steps at the several stations may-be concurrently car ried out at said stations on a plurality of bottles A or'their'equivalent. The machine is thus not only continuous in operation but also very rapid in turning out fully labelled articles.

If at any time during an operative period of the machine no bottle A is in place on the turntable II at the index station B, the index lever 40 at the moment the recount the cam 9| registers with the roller 81, will ,be swung on its pivot- IO by the action of the spring II to exert an upward pull on the link 42. The latter will thereby correspondingly move the 7 arm 44 to rock the shaft 04 and shift the roller 81 into said recess of the cam I.

As the shaft II is thus rocked on its axis, the bell-crank lever II will exert a pull to the left in Fig. 2, or to the right in Fig. 3, whereby a pull 7 in the same direction is exerted on the link I! A beneath and into'registry ,to close the valve I02. suction will be developed in the suction head 81 means for supporting 'aasasso and the control-member liltis swung onits pivot III to shift the upper end of said member ill with the one leg of the forked end I of the tripping member lill.

'lhe latter is thereby held againstydownward movement and the upper projection I" is p vented from acting on the bell-crank lever As a result of this, no

which at this stage is being transfer a label I! from the supply depositing station, and accordingly no label is removed from said stack. If a bottle A is present in the next successive receptacle IQ of the turntable 15, the aforesaid condition will be coroperated to chine will be resumed.
